Um, that's kind of weird, repayment for gifting? Shouldn't Naim be the sad one here, paying credits for something that would have been gifted? I think this is a bit backwards.
Shrug it off as an oops and forget about it, asking for repayment from giving the wrong gift is rude. Naim is the one who's out credits, not you, Woven, since your credits were spent on sending the gift. Naim is the loser in this case, who could have had 2 bundles instead of one had the wishlist been updated.
